Añejo tequilas must be aged for a minimum of 12 months. CORRIDO Añejo is an 18-month-old single-barrel añejo made from what they call a triple-barrel process. The triple-barreling process is more costly, as CRT must be notified each time they open a barrel, but that’s one of extra steps they’re willing to take to make their product unique. Silky yet intense with a powerful personality.
